When I look at my portfolio, I’m always amazed at how the stocks that performed best over the past decade weren’t the flashy tech darlings or the “next big thing” companies.
They’re always those businesses with something more subtle but far more powerful economic moat.
But what exactly is a moat, and more importantly, how can you spot one? Let’s talk about that.
Moat basics: What it means
If we think of it literally, a moat is a deep, wide ditch filled with water that surrounds a medieval castle, protecting it from invaders.
In business, an economic moat means a protective barrier for a company. It’s a sustainable competitive advantage that allows a company to protect its long-term profits and market share from competing firms.
Without a strong moat, competitors can easily encroach on a company’s territory, eating into its profits and market position.
Moat boils down to something that differentiates a company from its competitors, whether it’s superior service, lower costs, or a unique product feature that resonates with consumers.
It’s about creating a business that’s incredibly difficult for others to replicate or challenge.

Why moat investing works long-term
Now, you might be asking, “Willie, why is moat investing so important?”
Companies with robust economic moats tend to exhibit several key benefits, including predictable growth, monopoly power, and pricing power.
Companies with strong moats can often maintain high returns on invested capital over extended periods, even when facing economic headwinds or aggressive competition.
They’re more resilient because their competitive advantages allow them to weather storms that might sink less protected businesses.
This stability and consistent performance are a dividend investor’s dream!
1. Have unique assets (Intangibles)
One of the most powerful sources of an economic moat comes from having unique assets, often referred to as intangibles.
These aren’t your typical factories or equipment; we’re talking about the “hidden strengths” that give a company an undeniable edge.
A strong brand, for instance, is a highly valuable asset. Think about Starbucks. They can charge a significant premium for a cup of coffee compared to your local coffee shop, and customers are willing to pay it.
Why?
Because they’re paying for the recognisable “green mermaid” logo and the consistent quality and experience that come with the Starbucks brand.
This kind of brand loyalty protects a company’s profits by increasing customer willingness to pay and even allows them to raise prices during inflation or rising business costs.
Beyond brands, patents, intellectual property, and trademarks are also crucial intangible assets.
Pfizer, for example, relies on its portfolio of patent-protected drugs. These patents ensure high returns on their invested capital and the time it takes to develop new drugs, giving them a significant lead before generic competition can arise.
These unique assets are incredibly difficult for competitors to replicate, creating a tough barrier to entry.
2. Growing network effects
Imagine a product or service that becomes more valuable as more people use it. That’s the essence of a network effect, and it’s a potent source of an economic moat.
This concept leverages Metcalfe’s Law, which states that “The value of a network is proportional to the square of the number of connected users or devices”. The more people or devices connected to a network, the more valuable it becomes.
Social media platforms like Facebook and Instagram are a perfect example. The more users post content, the more new users it attracts, and the platform’s value increases exponentially as more users join.
The same goes for marketplaces like Amazon. As its user base grows, so does the value of its offerings, increasing with the expansion of its online platform.
A large user base creates a natural barrier to entry for competitors.
Why would a new user join a new social media platform when all their friends are already on an established one? This inherent advantage makes it difficult for new entrants to gain traction, giving established players a great competitive edge.
3. Command high switching costs
Have you ever considered changing your bank, but then thought about all the hassle involved in transferring direct debits, updating payment information, and potentially learning a new online banking system? That “hassle” is precisely what we call high switching costs, and it’s a powerful economic moat.
Businesses with high switching costs create big obstacles for customers to change providers.
These costs can be in terms of time, hassle, or money. These costs make it difficult for customers to switch, and competing products need solid improvements to convince customers to switch.
Apple is a prime example of a company with high switching costs.
If you’ve invested in music, TV programs, and movies through iTunes, it’s not easy to transfer them to other devices.
Similarly, iCloud synchronises all user data across Apple devices, creating another barrier to switching.
And once you’re an iPhone user, the thought of losing all your synchronised data by switching to an Android phone can be a huge barrier because their data can’t be synchronised with a different platform.
This integrated ecosystem creates a sticky customer base that’s hard for competitors to pry away.
4. Have a strong regulatory advantage
Sometimes, the government inadvertently (or intentionally) creates an economic moat through regulations.
These regulations can favour certain companies, allowing them to operate as virtual monopolies and making it incredibly hard for competitors to enter the market.
Take the Singapore Exchange, for example. It holds the exclusive license for securities and derivatives trading services in Singapore.
This licensing agreement grants them the sole right to operate, effectively preventing new entrants from establishing a competing stock exchange.
Another good example is the casino duopoly in Singapore, where only two licenses were granted: one to Marina Bay Sands (owned by Las Vegas Sands) and another to Resorts World Sentosa (owned by Genting Singapore).
These regulatory barriers ensure that these operators have a wider moat, significantly limiting competition.
Even in Macau, regulations state that licensed operators can open more than one casino with government approval, but operators must pay additional fees for each new casino. This kind of government-backed exclusivity is a powerful protective barrier.
5. Wide economies of scale
Wide economies of scale refer to a situation where a business can achieve a sustainable cost advantage over its competitors due to its large size or volume of operations.
This advantage often occurs from factors like a wide distribution network, being the lowest-cost producer, or having a strategic location.
Consider Walmart, the dominant US retailer. Its massive network of 4,700 stores, with 90% of the population living within 16 km of a store, creates incredible convenience for customers. This convenience drives customers to shop at Walmart.
Their sheer size and reach act as a powerful moat, allowing them to offer competitive prices and attract more customers. Since 2010, Walmart’s share price has more than doubled, excluding dividends.
When a market is best served by a limited number of competitors due to the cost structure, economies of scale come into play. This leads to higher returns for the dominant players and significant barriers for any aspiring new entrants.
Your turn: Find the moat
So, how do you find economic moats when you’re analysing companies? It’s not always immediately obvious, but by asking the right questions, you can uncover these powerful competitive advantages.
When evaluating a company, ask yourself:
For unique assets:
- What is the premium a company can charge versus its competitors?
- Is that premium offset by higher costs?
- How do their margins compare to competitors without strong brands?
- What gives you confidence that premium pricing and higher profit margins can be sustained over the next decade?
- And how do you quantify brand strength (what financial ratios do you look at)?
For network effects:
- How engaged are the users within the network platform or marketplace?
- Can users also get the same benefits from other network platforms?
- How is the company capturing the value of each incremental node added to its network?
- Can users duplicate such networks by partnering with one another and cutting out the platform entirely?
For high switching costs:
- What are the costs and benefits of customers switching products?
- Are customers’ assets and operations linked to a specific offering?
- How much lead time would a business need to be affected if a customer switched offerings?
For regulatory advantage:
- Are there any price controls in licensing agreements?
- What is the impact of adverse regulatory changes?
- Are there any threats of substitutes which bypass regulation?
For economies of scale:
- What is the cost of entering the market?
- What is the next marginal cost of production?
- How much market share can a new entrant take?
- Have new players tried to enter the market and failed?
By going through these questions, you’ll start to develop a keen eye for identifying the true sources of a company’s competitive advantage.
